Abstract
A roll fed copier is provided with mechanism responsive to depression of a copy button to start or turn on power to the machine and thereby initiate the feed of copy paper from a supply roll and to cock a sprng-powered knife which is tripped by linkage operated by an adjustable copy length control on the movable original carrying platen. Additional mechanism is also provided to break the power lines to the machines if the copy button is not actuated for a predetermined interval.
